2.6.18-164.el5 but redhat does a lot of backporting. i tried to compile
it on a centos 5 machine with ./configure --with-file-aio and get this

checking for Linux AIO support ... not found

../configure: no supported file AIO was found
Currently file AIO is supported on FreeBSD 4.3+ and Linux 2.6.22+ only


seems like centos 5 & redhat enterprise 5 are too old

but i have the following packages installed, regarding to aio

libaio-devel-0.3.106-3.2
libaio-0.3.106-3.2
libaio-0.3.106-3.2
libaio-devel-0.3.106-3.2

greetings
